It is generally accepted that a relatively low diastolic vascular pressure is more important than a relatively low systolic vascular pressure because: A. diastolic vascular pressure is the pressure that determines the length of diastole. B. diastolic vascular pressure directly determines stroke volume. C. diastolic vascular pressure ultimately determines and controls contractility. D. diastolic vascular pressure is a force the heart must compete with to open the aortic valve. E. None of the above is correct.
